Pharmacist tips for Acetic acid
- Only use acetic acid in the ear. Don't place the medication anywhere else in or on the body because it might be harmful.
- Use acetic acid ear drops exactly as prescribed. Don't change your dose or suddenly stop using the medication, even if your infected ear gets better. Stopping your treatment course too soon can cause the infection to come back and be harder to treat.
- Make sure to wash your hands before and after putting acetic acid drops in your ears. Don't let the dropper tip touch your ear or any other surface, and don't touch the tip with your hands. This helps prevent the ear drops from getting contaminated with germs, which will help you avoid future or worse infections.
- Gently clean and dry your ear before you use acetic acid. Remove all dirt and wax in the ear so that the medication can get in direct contact with the infected parts of the ear.
- How to use acetic acid ear drops: Lie down or tilt your head with the affected ear facing upward. Pull the ear back and upwards, and place the drops into the ear. Then, gently press the triangular piece of skin over the ear (the tragus) to help the medication get into the ear better. Keep the affected ear facing upwards for at least a few minutes. Use a clean tissue or cotton ball to lightly wipe away any extra medication that comes out of the ear after you get up.
- It's normal to feel some stinging or burning in the ear, especially when you first start using acetic acid, because of the inflammation in your ear. This should go away as the ear starts to heal.
- Talk to a healthcare professional if your symptoms (e.g., pain, itching, redness, hearing problems) don't start to get better after a couple days of using acetic acid. Swimmer's ear can sometimes become a more serious problem, so it's best to treat it as soon as possible.
- Store the acetic acid ear drop bottle at room temperature.
